[bldg-sim] Heat recovery savings w/eQuest looks low

[Randy Wilkinson]

Hello bldg-sim readers,

We have been enthusiastically using eQuest 3.55 for energy modeling 
recently.  However, savings for air-to-air heat recovery predicted seems 
to always be much lower than expected.  We are comparing savings to a 
spreadsheet that incorporates a bin method.   The bin method calculates 
savings that are believable including penalties for additional fan HP, 
etc.  I have looked in the (hard to use) archives for this list, but can 
not find anything that helps.  I am curious about the following:

What does it take to model heat recovery using the wizard?

What are the important inputs that effect heat recovery savings?

I have one model that I must use detailed edit mode.  How can I add heat 
recovery using detailed edit mode?

If you can help me or point me to where these Q's have already been 
answered, I would be forever grateful.

Randy
